Great! Post how you did it (include things like did you remove the old compound from the chips, what you put on, screw torque amounts, etc) so other people can do this as well.

The Ebay coolers are a bargain....

I believe you are correct, sir.

I can hear fluid when I shake it, but I can't hear any fluid moving when I turn it on. I can tell at least one of the pumps initiates, but the copper blocks heat up immediately, some shares are accepted and then when the temp reaches 85 they shut down. Too little fluid perhaps. I have ordered new cooling units, I'll see if that fixes the issue.

Another issue, I have a 700gh unit that only hashes at 320gh with bfg 4.10 and 400 with BFL custom bfg 4.2. Could this be another cooling issue with one of the units shutting down?

I have two Monarchs that seem to have faulty temperature sensors and they stop hashing very quickly after bootup. Any way to fix the problem?

I have another with 15% HW error rate, any ideas on this?

I received one box yesterday and one today. The first 3 were packed well and are in good condition. They hash just fine. I haven't opened the second box but I anticipate the same.

Good price for these even if they are inefficient. Good seller and I would buy from graymatter again.

I used the BFL BFGMiner variant here: https://bitcointalk.org/index.php?topic=759398.0
